Did high knees at 35 weeks pregnant and have intense lower ab and back pain

👩🏻

I did some running and high knees when pregnant. It was literally 10 seconds i did this. It felt fine. I went to dr after and babies heart beat was 161 and she didn’t do an ultrasound but she said everything seemed great. I was effaced and dilating. She also did a cervix check.

I’m worried I hurt the baby
